At first, a pail contained
37 ℓ of water. Pamela added another
12 ℓ of water into the pail. Then she used
513 of all the water in the pail. How much water did Pamela use? Express your answer as a fraction in its simplest form.
Total volume of water in the pail after Pamela added more water into the pail
= 37 + 12
= 614 + 714
= 1314 ℓ
13 u = 1314
1 u = 1314 ÷ 13 = 1314 x 113 = 114
Volume of water that Pamela used
= 5 u
= 5 x 114
= 514 ℓ
Answer(s): 514 ℓ
